Thread-topic: [Xen-users] cd-rom access, hvm boot, unstable download from 9-7-2006

Yes that solved the issue!


I am now fighting a no keyboard on xp installer issue, I can not specify the HAL to use as I have no keyboard in either VNC or SDL so I can not hit F5 or F7.

I am doing a yum update on the OS now to see if it may correct the problem.


Thank you for your help,

HVM configuration has been changed. “cdrom” item is removed and merged into disk item. You can follow /etc/xen/xmexample.hvm to modify your HVM configuration.

The new cdrom usage should like:

disk = [ 'file:/var/images/install.img,hda,w', 'file:/root/installimages/winxpsp2.iso,hdc:cdrom,r' ]

I grabbed the unstable download from 9-7-2006.


When I go to create a hvm VM, I get a CDROM boot failure code: 0002 in xm dmesg.


In my configuration file, I have tried the following:





Both without success.


Should I use a syntax like pointing the hard disk to an image?




cdrom = [ ‘file:/root/installimages/winxpsp2.iso’]


(this does not work either)


When I issue the xm create winxp.hvm command I get the SDL window and see a quick screen with a “Q to quit” prompt (too quick to read it all) then see the bios screen pop up, get a could not read from boot device error in that screen and it dies.



If anymore information is required please let me know.


The platform is an AM2 4600+ chip riding on an MSI K9N SLI Platinum with a gig of Corsair Dual channel DDR2 with a WD SATA 160 gig drive. Running CentOS 4.3 64bit.


Also is it best practice to give guest OS’s individual partitions or use image files for their operating system? I could see portability being a huge plus with image files but maybe better performance from partitions. Has anyone had a chance to play with this using fiber channel SANs? Is it worth the effort?
